Click For Summary
Bending salt crystals, particularly NaCl, for use in x-ray monochromator setups is a topic of interest for improving diffraction in radiation spectrum measurements. A saturated heated salt bath may be an effective method for deforming the crystals, specifically in the 111 plane. Practical insights are sought regarding the amount of pressure needed, mounting techniques, and whether pressure should be applied slowly or steadily. Participants in the discussion are encouraged to share any relevant experiences or alternative methods for observing wavelengths of unknown VUV soft x-ray beams. The inquiry highlights a need for practical guidance in this specialized area of x-ray diagnostics.

TL;DR
xray monochromator salt crystal bending
Has anyone ever attempted or know how to bend salt crystals for use in xray monochromator diagnostic setup of radiation spectrum measurements? I have heard that one could use a saturated heated salt bath to deform NaCl crystal to aid in diffraction of xrays in spectrum measurement setup. I am inquiring if anyone has any practical experience or know how to setup to deform the crystal in the 111 plane etc. Any information that maybe useful would be great! Specifically, the amount of pressure, mounting techniques use of setup where to apply pressure, is the pressure added slowly or steady etc. It is definitely a shot in the dark here. Or would something else be in order to observe the wavelength of an unknown VUV soft xray beam? Thanks!
 

Thread 'Does acceleration affect impact energy vs constant velocity?'

I do not have a good working knowledge of physics yet. I tried to piece this together but after researching this, I couldn’t figure out the correct laws of physics to combine to develop a formula to answer this question. Ex. 1 - A moving object impacts a static object at a constant velocity. Ex. 2 - A moving object impacts a static object at the same velocity but is accelerating at the moment of impact. Assuming the mass of the objects is the same and the velocity at the moment of impact...
